style=\"color:red\">方</span>、单斜和四<span style=\"color:red\">方</span>等多种晶体结构,其中六<span style=\"color:red\">方</span>晶相(h-WO3)由于具有开放结构而在气体传感器和电池电极等领域显示了突出性能,而单斜晶相(m-WO3)具有合适的带宽和良好的可见光响应性,因而广泛应用在光催化领域.而且,h-WO3的导带和价带均低于m-WO3的导带和价带,所以在WO3材料中有可能通过构建单斜/六<span style=\"color:red\">方</span>异相结(m-WO3/h-WO3)来提高WO3的光催化性能.本文借鉴半导体异相结概念,采用固相热分解法,试图通过调节焙烧温度和焙烧时间以构建m-WO3/h-WO3异相结催化剂.利用X射线衍射(XRD)、高分辨透射电镜(HRTEM)、扫描电镜(SEM)、X射线光电子能谱仪(XPS)和N2吸附-脱附等方法对WO3样品的晶相结构、形貌和元素组成等进行了表征.以光催化降解罗丹<span style=\"color:red\">明</span>B(RhB)为模型,研究了不同晶相WO3材料的光催化性能,考察了WO3晶相和异相结对其光催化性能的影响,从而为WO3材料中异相结的构建提供思路、方法和理论指导.结果表明,采用偏钨酸铵固相热分解制备WO3的过程中,焙烧温度为600-700℃时,样品为单斜晶相,随着焙烧温度升高至800℃时,样品中开始出现六<span style=\"color:red\">方</span>晶相.随着焙烧温度升高,h-WO3的含量没有明显变化,当温度升至1000℃时,h-WO3的含量有所减少.SEM和HRTEM结果验证了m-WO3/h-WO3异相结的形成,小的m-WO3粒子分布在棒状h-WO3上,并且两者紧密接触.为了进一步证实WO3的异相结效应,将偏钨酸铵在800℃焙烧不同时间(8-30 h).结果表明,通过改变焙烧时间可有效控制m-WO3和h-WO3混合晶相比例,800℃焙烧8h时m-WO3为主要晶相,焙烧12h时h-WO3含量明显增加,当焙烧时间延长至24和30h时h-WO3含量减少.SEM结果同样显示,在800℃焙烧12h样品中棒状h-WO3显著增多,与小的m-WO3粒子接触几率增大,即m-WO3/h-WO3异相结数量增加.不同晶相WO3样品光催化降解RhB的结果表明,具有m-WO3/h-WO3异相结结构的WO3催化剂具有较高光催化活性.荧光光谱结果表明,单斜相/六<span style=\"color:red\">方</span>相异相结的形成提高了电子-空穴分离效率,从而提高了其光催化降解RhB的活性.而在具有m-WO3/h-WO3异相结结构的WO3催化剂中,随着焙烧温度升高或焙烧时间延长,h-WO3含量有所减少,从而导致暴露的m-WO3/h-WO3异相结数量减少,因而使得活性有所降低.本文采用固相热分解法通过调变焙烧温度构建了m-WO3/h-WO3异相结光催化剂,显著提高了光催化降解RhB的活性,这对设计合成高效WO3基光催化剂具有一定借鉴.","authors":[{"authorName":"卢圆圆","id":"e7669a9f-4354-4833-ac88-d88d334212a7","originalAuthorName":"卢圆圆"},{"authorName":"刘果","id":"3c2fcde2-2ff5-4a53-a971-5916cf45c7bf","originalAuthorName":"刘果"},{"authorName":"张静","id":"90e980a4-a81d-41fa-b58e-ad356b7b68ff","originalAuthorName":"张静"},{"authorName":"冯兆池","id":"718594ae-adc2-46ec-baba-0ebd0e76cc0a","originalAuthorName":"冯兆池"},{"authorName":"李灿","id":"69129c24-ef50-46f5-a1e5-232684618036","originalAuthorName":"李灿"},{"authorName":"李智","id":"be930610-1f69-4516-a4a8-3a10a5a6f966","originalAuthorName":"李智"}],"doi":"10.1016/S1872-2067(15)61023-3","fpage":"349","id":"68b45c23-3251-4602-894d-b4af330f3d9e","issue":"3","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报
